five equal horizontal bands of blue (top, center, and bottom) alternating with white; a red equilateral triangle based on the hoist side bears a white, five-pointed star in the center; the blue bands refer to the three old divisions of the island: central, occidental, and oriental; the white bands describe the purity of the independence ideal; the triangle symbolizes liberty, equality, and fraternity, while the red color stands for the blood shed in the independence struggle; the white star, called La Estrella Solitaria (the Lone Star) lights the way to freedom and was taken from the flag of Texas
